Group - Performance: Ping Availability

This performance report displays ping availability data collected during the selected time period from the device group displayed at the top of the report. You can configure the data collection for individual devices through Device Properties > Performance Monitors > Configure Ping Latency and Availability.

Device. The network device.
Interface. The network interface.
Packets Sent. The total number of packets sent throughout the current group during the selected time period.
Packets Lost. The total number of packets lost throughout the current group during the selected time period.
Percent Packet Loss. A percentage of packet loss throughout the current group for the selected time period.
Total Poll Time (minutes). Amount of total time (in minutes) that passed during the time period selected..
Time Unavailable (minutes). Amount of total time (in minutes) that a device was unavailable in the group.
Percent Available. The total availability percentage averaged over all samples during the selected time period.

The Device Data table displays the same information as above, but on a per device basis.

Note: The Percent Available is a weighted average of availability for all data entries. It is not a simple average of percent availability for each entry. The value for the total availability percentage is reached by: multiplying the availability percentage with the amount of time that passed between polls to get a sum for each entry. Add those sums and divide by the sum of all time periods between polls.

Note: Values displayed in the table are the average values for the selected time period. Values displayed in the summary are the minimum, maximum, and average values for the selected time period. If raw polling data has been averaged into hourly or daily summarized data, the values for min and average, or maximum and average can be different. In some cases, they may be very different if there was a period of time when polled values were much higher or lower than normal.

You can verify your report rollup settings on the WhatsUp Gold console via Program Options > Report Data.

Packets Lost. The total number of packets lost over the selected time period by the monitored interfaces.
Total Poll Time. The total amount of time in minutes the monitored interfaces were polled.
Time unavailable. The total amount of time the monitored interfaces were unavailable.
Percent Available. The percentage of the amount of time the monitored interfaces were available.

Thresholds

Report percentages are displayed in colors that represent the CPU utilization thresholds:

Red. above 90%
Yellow. above 80%
Green. 80% or less

Changing the report date

Use the date/time picker at the top of the report to select a date range and time frame.

In the Date range list, some reports also allow you to specify and customize the business hour report times for reports to display. This allows you to view the network activity only for specified business hours. The date and time format for the date on this report matches the format specified in Program Options > Regional set in the WhatsUp Gold console.

Paging Options

At both the bottom and the top of the report table exist report paging controls that allow you to move through extensive amounts of report data with ease. First, use the Page list to select the specific page for which to view report data. Next, use the Showing ___ rows per page list to specify the number of rows that you would like displayed in the report. You can choose to display 25, 50, 1000, 250, or 500 rows. The default maximum is 50 rows. Finally, the Paging buttons allow you to move from page to page, or go to the first or last page.
